@riginal `application. nleri September 2, 1913, Serial t'o. 787,745.Divided and this application filed June 29, 1914. Serial No. 843,043.

To all whom it may concern Be it known that we, MAX lDNNEBIER and ALFREDWINKLER, citizens of the German Empire, residing at Neuwied-on-the-Rhine, Germany, have invented certain new and useful Improvements inDelivery and Counting Mechanism, of which the following is aspecification.

This invention relates to improvements in delivery and countingmechanism suitable for use in envelop and bag making machines such forinstance as described in our copending application Serial No. 787,745from which the present application has been divided out.

The main object of this invention is to provide improved means by whichthe bundling device, which may be of any kind, will not operate toseparate the bundles unless the proper number of envelops has beenpassed into the stack or receptacle. Various forms of bundling devicesare known and we have chosen only one to illustrate this invention,which however is applicable to other forms of bundling mechanism.

1t is not necessary here to illustrate the entire machine for making theenvelops as this is described in greater detail in our copendingapplication mentioned above. The counting mechanism is arranged at thedelivery end and its moving parts are operated by suitable driving ortransmission mechanism from the main driving shaft of the machine.

1n the drawings: Figure 1 is a side elevation showing the entiremechanism, one side frame of the machine has been removed together withclutch mechanism located on the shaft 123 externally of the removedframe. Fig. 2 is an end elevation of so much of the machine as is shownin Fig. 1. Fig. 3 is an end view of the external clutch, this view beingsimilar to Fig. 2 from which this part has been omitted. Fig. 4 is adetail of the single revolution clutch mechanism and Fig. 5 is a furtherdetail which is not distinctly visible in Fig. 4.

For the purpose of this invention the envelops passing from the machineare delivered into a suitable receptacle for the counted bundles. Thisreceptacle is fashioned with a number of compartments and when thedesired number of envelops has been filled in to one of the uppercompartments,

the receptacle is moved on to bring a fresh compartment into position toreceive the' envelops discharged. The envelops thus filled and countedin the compartments of the storage drum are delivered in bundles to thedelivery stack.

The envelop passing from the roller 90 and sector 99, is taken up by asuction nozzle 108. The sector 99 is short and does not complete thetransportation of the blank. The suctlon nozzle 108 completes thetransportation or delivery of the blank and for -th1s purpose is mountedon a hollow shaft 109 (see Figs. 1 and 2) connected to a vacuum pump notshown by a dexible pipe 110. The hollow shaft 109 is adapted to beoperated by a lever 4111, and a forked rod 112, which 1s provided with aroller engaging a cam 1.13, mounted on the axis of thek roller 90,sultable spring means, not shown, being employed to retain the roller incontact with cam' 113. The nozzle 108 is adapted to swing inthedirection of the arrow in Fig. 1 to transport the envelops downward andproperly into the compartment for the time being immediate in positionto receive these envelops.

The compartments are` open ended and formed by bars 115 fixed to acentral hub 114. The hub 114 is mounted on a shaft 11.7 provlded with aratchet wheel 116, so that the drum rotates in a vertical plane. An arm118 is mounted to rotate freely on the shaft 117, and this arm isoperated by a rod 120, which is forked at its lower end (see Fig. 2) andcarries a roller 122 engaging a cam 121 fixed to rotate with the shaft123. The shaft 123 is.operated from the main shaft. so as to rotate atintervals through a complete revolution and thereby the pawl 119 movesthe ratchet 116 and shaft 117 through an angle suficient to bring afresh nism so as to -rotate for one revolution with the main shaft.Means are also provided by which the forward feeding of the receptaclesis cut out if the proper number' of envelops has not been delivered. Theforward movement of the receptacles is thus not dependent wholly yuponthe proper number of operations to the pawl, but is also directlydependent upon the proper delivery of twenty-five, or other desirednumber of envelops to the compartment.

On the shaft 123, a twentyfive toothed wheel 124, is loosely mounted. Inthis wheel there engages a pawl 125 mounted on an arm 126. The arm 126is operated through a rod' 127 from the main shaft of the machine. Thisoperation is effected through a cam on the main shaft which causes therod 127 4to reciprocate. The stepby-step movemet of the wheel 124.brings a striker projection 129 against a lever 130 whereby the anglelever 130, 132, pivoted at- 131, receives a kick. The rod 133, which iscoupled to the end of the arm 132 operates a member 134 (see Figs. 3 and4) loosely.

mounted on the shaft 123, outside the frame of the machine. Thisexternally projecting part of the shaft 123 is omitted in Fig. 1. Thehubof the member 134 is Aprovided with a projection 134a (see Fig. 5)opposite a roller 135a mounted on the end of atransverse lever 135.

The lever 135 is pivotally mounted at136 on a hub 137 ixed to the shaft123. Alongside and in addition to the hub 137, a second hub 138 isloosely mounted which hub carries the chain wheel 139, and also theclutch ring 140, which resembles a ratchet wheel in shape. The member134 is loosely mounted around the second hub 138. .When the member 134is operated by the kicking of the lever 130--132, the projection 134 ismoved from beneath the roller 135 on the lever 135, and this lever ispressed by its spring 141 downward, so that it swings about its pivot136 into the path of the clutch projections on the clutch ring 140. Thefirst projection to engage the lever 135 causes this lever andthe sleeve137 and shaft 123 to rotate until the roller 135 again engages theprojection 134a to raise the lever 135, against the action of its spring141 out of engagement with the clutch projections on the ring 140. Therotation of the shaft 123 takes place inthe direction of the arrow Hshown in Fig. 4. It will be understood that the chain wheel 139 iscontinuously driven from the main shaft of the machine and the actiondescribed for rotating the shaft 123, only takes pla-ce when the propernumber of envelops has been delivered and counted by the counter ratchet124. The means described as operated from the striker 129 thusconstitute mechanism by which the envelops are automaticallyseparatedinto bundles of a desired predetermined number. As mentionedv above therotation of the shaft 123 raises the rod 120 and thereby causes the pawl119 to move the hub 114, through a suitable angle. The parts coming intooperation for producing this eifect` lis arrested, and these assume theposition shown in dotted lines in Fig. 1. The next following bar or bars115 sweep the bottom ends of the envelops of the arcuate guide 143-fromwhich they fall on to the table 147. Before this happens, however, thepusher 146, which is carried by the arm 145, is moved back by the rolleron the arm 145 following the cam 149. The arm 145 is pivoted about thepin 148 and is held by means of a spring (not illustrated) with itsroller against 'the cam 149. The parts 150, 151, 152 are arranged in aknown manner to displace the successive bundles slightly as regards oneanother when they are pushed up by the pusher 146. Simultaneously withthe retreat of the pusher 146, the fingers of the rake 153 are swungupward, in virtue of their carrying lever 156, which is pivoted at 154to the side frame of the machine (see Fig. 2) following the cam 155. Assoon as the pusher 146 has returned the bundle of 105 envelopsintoproper position Iin the pile, the fingers of the rake 153, againswing into the position illustratedl in Fig. 1.

The means for preventing the forward feeding of the receptacle with thecompartments for the bundles of envelops when the full number ofenvelops has not been delivered will now be described. More correctlythe means to be described insures that the .single rotation of the shaft123 is dependent upon the proper delivery of the proper number ofenvelops to any given compartment. When through any reason no blank isdelivered from the sector 99 and roll 90 the suction nozzle 108 is notclosed by the euvelop and in consequence no material vacuum is set up inthe hollow shaft 109 connected to said nozzle. Alongside the nozzle 108,a hollow arm 158 is provided, also in communication with the hollowshaft, and inywhich a piston 157 is adapted to work against the actionof a spring 159, when the suction action is set up in the hollow shaft.When no material vacuum is formed in the hollow shaft 109, the spring159 maintains manana the piston 157 at its extreme outer positionillustrated in Fig. 1. The piston 157, by its position determineswhether or not the counter tripping mechanism herein described isoperated or not, and its position is in turn dependent upon theengagement ot the suction nozzle with a blank. 'llhe tripping mechanismemployed may be ot any convenient form and the following has provedsuitable and eective: vThe piston has a rod 160 adapted, when the nozzle108 swings downward and when the piston 157 is in the positionillustrated, to engage with its roller end a lever 161 pivoted at 163,and carrying an arm 162 coupled by a rod 1611 to a twoarmed lever 166and 167 pivoted at 165. rlhe arm 167, when oscillated bv the roller onthe rod 160,'engaging the 5 rer 161 is adapted to strike against a taila 1G58 on the pawl 125. The pawl 125 is thus held out of engagement withits ratchet 1 that the movement of the arm 1% t rod 127 does not 'teedthe ratchet through one tooth.

1t will be understood that normally the piston 157 is drawn upward inFig. 1 by the suction created in the hollow shait 109 and thereby drawsthe end 160 out of the path of the lever 161 and the stopping actionabove described only takes place when no blank is delivered. ln order toenable the rod 160 to pass the lever 161 in its extended position theend of the lever 161 is provided with a pivoted finger 161a which istree to swing independently of the lever 161, when the rod 160 moves inthe opposite direction to the arrow shown.

The tripping mechanism described may be coupled up in any well blownmanner to the clutch tor putting the machine in and out of gear. i Thismechanism is usual on high speed envelop making machines and need not bedescribed more fully here.

'llhe invention may be applied to envelops and paper bags ot widelyvarying shapes and sizes.

We claim:
